NextSense Presents the CALIPRI Optical Measurement System at the CONTROL
- NextSense GmbH, the innovative provider of optical sensor technology,
will present the CALIPRI called non-contact multi-platform method for
the quick recording and flexible analysis of gap contours at the CONTROL
2013 trade fair in Stuttgart (hall 5, booth 5401). "CALIPRI meets the
requirements of the automotive industry for ever narrower gap dimensions
and measurement solutions independent of platform," said Christoph Böhm,
Marketing Manager at NextSense. "The optical measurement system allows
for measurements of an accuracy unknown up to now as well as the
universal use of one and the same measurement device in all stages of
automotive body production" ...

Abstract - The
main goal of the ESPIRIT project "Microintegrated Intelligent
Optical Sensor Systems" (MInOSS) was to investigate a design
methodology for optical sensor systems. This methodology was applied to
the design of a library of modules and general building blocks in
standard CMOS technology aimed at making the design of future optical
sensors easier. A set of demonstrators was developed, including a linear
array of sensors for spectrophotometry and a number of 2D sensor array
for use in "intelligent" digital cameras. The main results of
the project to be reviewed in this paper include library photodiode
arrays and charge amplifiers; three-step flash and algorithmic
analog-to-digital converters for on-chip conversion; the linear and 2D
intelligent sensor architectures which were developed; and guidelines
for the practical design of photosensors and pixel arrays in a mixed
analogue/digital/optical environment.

Abstract - The
use of CMOS technology allows the monolithic integration of photosensor
arrays together with analog-to-digital (A/D) conversion circuits. The
structure of the array can be exploited to increase the connectivity
between the sensor and the converter, which are in close coupling. Both
single-converter per array and multiple-converter per array approaches
are therefore possible. This paper presents a comparative study of
different A/D conversion architectures incorporated in intelligent
optical systems. The presented schemes have been validated by
experimental evaluations.

Abstract - This
paper presents a comparative analysis of different analog-to-digital
conversion architectures optimized for operation in close coupling with
optical sensor arrays in the presence of stringent design constraints
such as signal and noise levels, conversion rates and physical size of
the array. Architectures based on a single converter per array and on
multiple converters per array are considered. Measurement results on
dedicated converters integrated in experimental chips together with
optical arrays have proved the validity of the architectures presented,
with different trade-off points in terms of power consumption,
conversion rate and spatial uniformity.

Abstract:
The current status of optical fiber sensors is reviewed. The optical fiber sensors have certain advantages that include immunity to electromagnetic interference, lightweight, small size, high sensitivity, large bandwidth, and ease in implementing multiplexed or distributed sensors. Strain, temperature and pressure are the most widely studied measurands and the fiber grating sensor represents the most widely studied technology for optical fiber sensors. Fiber-optic gyroscopes and fiber-optic current sensors are good examples of rather mature and commercialized optical fiber sensor technologies. In this paper, among the various fiber-optic sensor technologies, especially, technologies such as fiber grating sensors, fiber-optic gyroscopes, and fiber-optic current sensors are discussed with emphasis on the principles and current status. Today, some success has been found in the commercialization of optical fiber sensors. However, in various fields they still suffer from competition with other mature sensor technologies. However, new ideas are being continuously developed and tested not only for the traditional measurands but also for new applications.
